IMPROVEMENT IN SHEARS.

Specication forming part of Letters Patent No. 176,520, dated April 25,1876; application filed March 21, 187 6.

To all whom it may concern Be it known that I, HENRY DORNBURGH, ofOlxnsteadville, Essex county, New York, have invented a new and'Improved Shears, of which the following is a specication My inventionconsists of a bar for the support of the pivot, supported on one of theblades outside of the other blade, so 'that the pivot has a bearing ateach end, and sustains the strain in the middle, in suchmanner that inconnection with broad bearings the blades are prevented from openinglaterally along the edges, asA they do when the pivot goes through oneblade and screws into the other.

Figure 1 is a plan view of my improved shears, and Fig. 2 is a sectionon the line m m.

Similar .letters ot' reference indicate correspondingparts.

A represents the bar, which is attached to the blade B on opposite sidesof the blade C, and supports one end ofthe pivot D, While the other endis supported in the blade B, the blades being constructed with broadbearings b c around the pivot-holes, so that the pivot is prevented fromWabbling, and the blades are retained in their positions relatively toeach other.

Having thus described my invention, I claim as new and desire to secureby Letters Patenty The combination of bar A and broad bearings b c withpivot D, to prevent the shears from turning and cutting each other,thereby injuring the edges.
